Effects of Mould on Crimping of Large Diameter Welding Pipe

Abstract:

Crimping is widely used in production of large diameter submerged-arc welding pipes. In crimping process, mould is one of the main factors which influences the quality of forming and should be considered at the stage of designing the forming die and process. So, Effects of mould on crimping is researched using finite element method. Taking the crimping of X80 steel Φ1219mm×22mm×12000mm welding pipe for instance, the crimping forming process is simulated by finite element (FE) code ABAQUS. In this paper, the simulation data is validated by product and a comparison showed a good agreement with product results. The stress/strain from simulation is discussed. Thus, the results of research provides a basis to choose mould.
